Embodiment Construction

[0032] [32] Such as figure 1 As shown, the passenger railway vehicle 2 has passenger carriages 4 which are defined by side surfaces 6, a floor 8 and a roof 10.

[0033] [33] In the rest of this specification, the “top” of the cabin refers to the cabin space near the roof 10, and the “bottom” of the cabin refers to the cabin space near the floor 8.

[0034] [34] The vehicle 2 has an air conditioning system 12 for a compartment 4, which includes: an air conditioning unit 14 for generating cooled air or heated air; and distributing the air generated by the air conditioning unit 14 to the bottom of the compartment 4 The first net 16; and the second net 18 that distributes the air generated by the air conditioning unit 14 to the top of the compartment 4.

[0035] [35] The air conditioning unit 14 includes: a main air processing unit 20 for air heating or cooling; a set of power blower units (GMV) 22 for forcing airflow through the air processing unit 20; for supplying air to the first ne...

Abstract

Air conditioning system comprises an air treatment arrangement for distributing a first air stream (F1) and a second air stream (F2) with different temperatures in a first network (16) and in a second network (18). Independent claims are also included for the following: (1) Rail vehicle with the above air conditioning system; and (2) Method for conditioning the air in a compartment of a rail vehicle. Preferred Features: The air treatment arrangement comprises a common main air treatment unit (20) for supplying air to the first and second networks and an auxiliary air treatment unit (28) for separately treating the air stream in one of the networks.

Description

Technical field [0001] [01] The present invention relates to an air conditioning system for a vehicle compartment. This type of air conditioning system includes: [0002] [02] Air treatment devices for heating and / or cooling air; [0003] [03] The first net for distributing air to the bottom of the car, and [0004] [04] A second net used to distribute air to the top of the car. Background technique [0005] [05] Document EP 1 442 954 A1 describes an air conditioning system for railway vehicles of the aforementioned type, which includes a distribution device that distributes the treated air toward the first net or the second net so that more Air is supplied to the top of the car or more air is supplied to the bottom of the car. [0006] [06] Of course, such a system cannot maintain the temperature with a controlled temperature gradient between the top and bottom of the railway carriage, and therefore cannot guarantee the comfort to the passengers. Summary of the invention [0007] [07...
